This auxiliary high-limit switch monitors temperature at a secondary location — typically near the blower or heat-exchanger area — and opens the circuit to shut down the furnace if it detects an overheat condition caused by restricted airflow, a dirty filter, or blower failure. Because it is an auto-reset design, it re-closes and restores operation once the temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20269903\u003c\/li\u003e\n\u003cli\u003ePart Type: Auxiliary Limit Switch\u003c\/li\u003e\n\u003cli\u003eReset Type: Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003eFunction: High-temperature safety cutoff\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMV81155CXBA (Goodman\/Amana two-stage furnace)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific cutout and reset temperature for this furnace.
